GRASS Commands

r.in.ascii -f input=C:\Documents and Settings\jc152199\Desktop\GRASS\bigbuffer\PERMANENT\dem250bigbuffer.asc output=dem250bigbuffer

### The above command worked to read in an ASCII file and convert to a GRASS raster file

r.slope.aspect elevation=dem250bigbuffer@PERMANENT slope=slope250bigbuffer aspect=aspect250bigbuffer

### The above command worked to create a raster of slope/aspect from the DEM raster

r.sun -s --overwrite elevin=dem250bigbuffer@PERMANENT aspin=aspect250bigbuffer@PERMANENT slopein=slope250bigbuffer@PERMANENT linkein=ltcheck@PERMANENT beam_rad=beamrad insol_time=insoltime diff_rad=diffrad refl_rad=reflrad day=106

### The above command created some raster layers, I have no fucking clue if they're correct

r.sun -s --overwrite elevin=dem250bigbuffer@PERMANENT aspin=aspect250bigbuffer@PERMANENT slopein=slope250bigbuffer@PERMANENT linkein=ltcheck@PERMANENT beam_rad=beamradwithstep insol_time=insoltimewithstep diff_rad=diffradwithstep refl_rad=reflradwithstep day=106 step=.5

#### Same as above, except I put in step and changed the names of outfiles accordingly
